The inspiration for this chat occurred to me this weekend when I finally bought and started using an extra long iPhone charging cord, so I could simultaneously charge my phone and lie all the way over on the far side of the bed, rolling around freely while staring at Instagram when I am supposed to be sleeping, as if truly untethered.  I got this set of long charging cords from Amazon, it cost me $11, and has immeasurably improved my life. And this got me to thinking: What item do you own that costs less than $20 that has made a real difference in your life? Please share!
